Description

[Detailed description of the invention] A. Field of industrial application The present invention relates to an opening/closing mechanism for a lid in a disc player device.

(b) Prior art When a disc is mounted on a disc player device, the disc is placed on a disc holding stand that is pulled out from the disc mounting port provided on the disc player main body to the outside of the mounting main body, and the disc is driven. For example, Japanese Patent Laid-Open No. 58-45656 proposes a disk player in which a disk holding table on which a disk is placed is housed inside the main body of the device. The disk mounting opening is opened and closed by a lid that moves linearly in the vertical direction, and this lid is controlled in response to the movement of the disk holding base. However, in this conventional example, the cam surface of the lid comes into contact with the lower end of the horizontally moving disk holding table, and the opening/closing control of the lid is not necessarily smooth.

C. Purpose of the invention The present invention aims to smoothly control the vertical opening and closing operations of the lid body in relation to the movement of the disk holder.

D. Structure of the invention The invention includes a disk holding stand that can be rotated to two positions, a disk mounting position and a disk driving position, and a lid that moves linearly in the vertical direction to open and close the disk mounting opening provided in the cabinet. A communication member rotatably supported by the cabinet communicates with the body. That is, one end of the communication member is in contact with the disk holding base, and the other end is in contact with the lid. Therefore, the rotational movement of the disc holding base is smoothly transmitted to the lid through the communication member, and the lid moves in the vertical direction to open and close the disc mounting opening.

E. Embodiment FIG. 1 shows a front view of the main body of the disc player apparatus, and the lid body 2 is
is provided, and opens and closes the disk mounting opening 1 by moving up and down. Figure 2 shows the disk holding base 3 pulled out to the outside of the device.
The disk D is attached to the disk holding base 3 in this pulled out state.

Figures 3a, b and c show the lid closed, and Figures 4a and 4b show the lid open. The lid body 2 is
It has bent portions 2a at both ends, and these bent portions 2a are inserted into elongated holes 5a of a pair of brackets 5 provided in the chassis 4, and are guided by the elongated holes 5a to be able to move up and down. ing. The lid 2 is always urged downward (in the lid opening direction) by a coil spring 6 stretched between the lid 2 and the chassis 4.

The disk holding base 3 that holds the disk includes a rotating member 7 rotatably supported on the chassis 4.
and a disk storage frame 8 placed on this rotating member 7. Note that the pivot point of the pivot member 7 is not shown.

The rotation of the rotation member 7 is transmitted to the lid body 2 by a pair of communication members 9 rotatably supported on the chassis 4. A pair of communication members 9 are connected to a pair of brackets 10 provided on the chassis 4.
It is rotatably supported around a shaft 11.
The bent portion 9a at one end of the connecting member 9 is in contact with the lower end of the bent portion 7a of the rotating member 7, and the bent portion 9b at the other end of the connecting member 9 is in contact with the lower end 2a of the lid body 2. There is.

Figures 3 and 5a show the lid closed state,
In this state, the disk holding base 3 is at the disk drive position. Therefore, the disk D stored in the disk storage frame 8 is placed on a disk driving turntable (not shown) provided on the chassis 4 and is rotatable. . The disk holding base 3 has a coil spring 12
The lower surface of the rotary member 7 abuts against the cam surface 13a of the cam gear 13 at the position shown in FIG. 5a, thereby positioning the rotary member 7 at the disk drive position.

It should be noted that the disk holder 3 is not shown in FIG. 3a.

To change the lid from the closed lid state (disk drive state) to the open lid state (disc mounted state), use the cam gear 13.
It is sufficient to rotate it in the direction of the arrow shown in FIG. The cam gear 13 rotates as the rotation of the cam gear driving motor 14 is transmitted via reduction gears 15, 16, and 17.

When the cam gear 13 rotates and the cam surface 13a pushes up the lower surface of the rotating member 7, the rotating member 7 is rotated upward against the urging force of the coil spring 12. Then, the lid body 2 is moved downward, that is, in the lid opening direction, by the biasing force of the coil spring 6. Fourth
The figure shows such an open state. Note that the urging force of the coil spring 12 is naturally stronger than that of the coil spring 6.

After that, when the cam gear 13 rotates further, the gear 13b of the cam gear 13 engages with the gear 8a provided on the underside of the disk storage frame 8, and the disk storage frame 8 moves along the upper surface of the rotating member 7 and is pulled out to the outside of the device body (see Figure 5b and Figure 2).

The rotary lever 18 is for stably holding the disk holding base 3 at the disk mounting position, that is, the position shown in FIG. 4. That is, at the position,
The front left side of the disk holding base 3 is in contact with the cam gear 13, and the front right side is in contact with the shoulder 18 of this rotary lever 18.
It comes into contact with a. The rotating lever 18 is pivoted 20 to a bracket 19 provided on the chassis 4, and is biased upward by a spring 21 so that the tip of the rotating lever 18 follows the lower surface of the rotating member 7. It is configured so that it can be moved. Then, as shown in FIG. 4b, the bent portion 7 of the rotating member 7
When a comes into contact with the shoulder portion 18a of the rotating lever 18, the right side of the disk holding base 3 is held.

F. Effects of the invention According to the invention, since the rotation of the disc holder is transmitted to the lid via the rotating member, the opening/closing operation of the lid can be smoothly performed in response to the rotation of the disc holder. will be achieved.
